Abstract
PCT No. PCT/SE80/00089 Sec. 371 Date Dec. 25, 1980 Sec. 102(e) Date Nov. 19, 1980 PCT Filed Mar. 26, 1980 PCT Pub. No. WO80/02316 PCT Pub. Date Oct. 30, 1980.A quick coupling device for fluid tight, especially temporary connection to a threaded pipe nipple (2) or the like, e.g. for use in tightness tests or leak detection. The device comprises two portions which are axially movable relative to each other, namely a cylindrical casing (3) and a piston (4) displaceably mounted therein. The casing and/or the piston are adapted (5) for permanent connection to a pressurized fluid conduit, and the piston has a through opening (9) permitting the flow of pressurized fluid to the pipe nipple (2). According to the invention, one (e.g. the piston (4) of the axially movable portions is provided with a thread dimensioned to be screwed into engagement with the thread of the pipe nipple (2), whereas the other portion (e.g. the casing 3), at its axial end surface, has a ring gasket (8) dimensioned to seal against the axial end surface of the pipe nipple upon screwing said one portion (4) into engagement with the pipe nipple and displacing the other portion (3) axially against the pipe nipple (2). (FIG.
